Non-Volatile Memory: Data Retention Explained
Non-volatile memory is a type of computer memory designed to maintain stored data even when the power supply is completely removed. This characteristic makes it ideal for long-term storage.
Key Characteristic
- Power State: The defining feature of non-volatile memory is its ability to retain information when the device is not powered.
Analysis of Options
- Correct Option: not powered - This aligns with the definition; non-volatile memory keeps data without electricity.
- Incorrect: not processed - Processing is an action performed on data, not a condition for its storage persistence.
- Incorrect: intermittently powered - While data might persist briefly during power fluctuations, the defining characteristic is retention *without* any power.
- Incorrect: powered - Volatile memory (like RAM) typically requires continuous power to retain data. Non-volatile memory's key advantage is its function when power is *off*.
Therefore, non-volatile memory retains information even when the computer is not powered.
